            Bug ID: 1406
           Summary: "net/ice" and "net/i40e" have not implemented outer
                    UDP checksum offload, but the capability flag has been
                    set.
           Product: DPDK
           Version: 23.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: junwang01@cestc.cn
  Target Milestone: ---

As shown in [1],a geneve packet with TSO request is transmitted, and resulting
packets mismatch because of the wrong checksum in the outer UDP header (it is
the same as the one in the original superframe). However, since the test sees
capability bit TX_OFFLOAD_OUTER_UDP_CKSUM in device info, the checksum is
expected to be offloaded.

Both X710 and E810 encounter the same issue. Upon reviewing the unloading
portion of the code, it's evident that only adding capabilities without
unloading part of the code was implemented.
